It is generally accepted that the founding fathers of the wondrous espresso machine were Milanese inventors/manufacturers Luigi Bezzara, who patented his espresso machine in 1901, and Desidero Pavoni, who bought the patent from Bezzara 1903 and released his own machine in 1905.
However, it was actually Angelo Moriondo who holds the first patent for an espresso machine dating back to 1884. His bulk espresso machine was used to serve coffee at the Turin General Exposition in 1884–nearly 20 years before Bezzara and Pavoni.
